Municipal drainage rainwater and sewage diversion treatment device

Abstract

The invention discloses a municipal drainage rainwater and sewage diversion treatment device. The rainwater and sewage diversion treatment device comprises a box body, a switching structure and a residue filtering structure; the switching structure and the residue filtering structure are arranged in the box body, and the switching structure is in pipeline connection with the residue filtering structure; the switching structure performs rainwater and sewage diversion according to different densities of sewage and rainwater; and the residue filtering structure is used for filtering impurities inthe sewage through backflow. The switching structure is used for shunting the sewage and the rainwater according to different densities of the sewage and the rainwater, meanwhile, the residue filtering structure is used for shunting the impurities and the water through backflow so as to remove the impurities, thus the siphon principle is used for settling the impurities in the sewage, and the effect of quickly switching flow channels is achieved.

Description

technical field [0001] The invention relates to the technical field of rain and sewage diversion, in particular to a rain and sewage diversion treatment device for municipal drainage. Background technique [0002] With the development of the economy and the enhancement of environmental protection awareness, water resources are becoming more and more precious. In order to make better use of rainwater resources, our country implements the drainage method of using a municipal drainage pipe for rainwater and sewage, that is, rain and sewage diversion. Rain and sewage diversion refers to the sewage discharge method that separates rainwater and sewage and transports them through a pipeline for discharge or subsequent treatment. The rainwater is directly discharged to the river through the rainwater pipe network, and the sewage is concentrated through the sewage pipe network and sent to the sewage treatment plant for treatment, so as to avoid the sewage directly entering the river ...

AI Technical Summary

Problems solved by technology

However, the amount of rainfall cannot completely serve as a condition for the diversion of rain and sewage. When the previous rainfall is large, the amount of sewage will also be large, and the buoy will also rise and block the entrance of the sewage pipe network, so that the sewage directly enters the river. , causing pollution of the river

The rain-sewage separation device in the prior art is not easy to distinguish sewage and rainwater, and rarely can accurately separate the sewage and rainwater. Therefore, people need a municipal drainage rain-sewage diversion treatment device to solve the above problems
